Are opinions like folk medicine…i.e. Bach Flower Remedies…?? no clear evidence of cure…

Are all opinions based on bias or evidence or accurate knowledge?

Yep, trees grow…exist… not an opinion?… a nature fact…and evidence shows not all trees produce the same wood “quality”…soft, hard wood, etc… needed/used for different wood-working projects/products.

It is a fact… for example, generally speaking, pine wood is easy to shape and stain. Wood serves a purpose, has a purpose (for carpenters, eh?)… do skilled/master carpenters…lump all wood in the same wood pile… or “choose” specific or various woods and density for individual-specific projects? (I am no carpenter. I am no tree designer.)

wood selection is the discretion of the carpenter…
Oh ya, and for this blog to have mass appeal…I must include…or recognize there are some of us who don’t believe in (a)carpenter(s)… who “think” well-constructed houses or shacks just pop out of the ground all on their own…by chance.

Just expressing… there is a difference between an opinion and a fact…(and theory and practice) just like there are factual differences in trees, woods, and products… aka results/proof from wood-working.
